Description:
These wall-mounted eye/face washes feature dual spray heads activated by a stainless steel push handle.
Catalog Number:
(470165-140)
Description:
Experiment with gear ratios on your wind turbine or other small projects. Adding gears to your turbine can greatly increase the generator RPM, giving you higher power output. The small 8-tooth gear fits on 2 mm driveshafts that are found on many DC generators. The gears have a keying feature that allows them to be changed quickly and easily using the included hex locks. The hex lock secures to our 9/64 inch hex-driveshaft. Hex-driveshaft not included.
Description:

Description:
Tubes are designed for routine use in immunohematology testing and viral marker testing in screening and clinical laboratories.
Catalog Number:
(470162-714)
Description:
Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair (not included). By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge (e/m) and the velocity of the electrons.
Catalog Number:

Description:
Mounted on molded plastic base, the unit consists of a base into the top of which may be screwed one of a set of four vases of differing shapes. An aperture in the bottom has a thin rubber diaphragm across it, bearing upon the short arm of the lever pointer. A moveable index on the vertical rod enables the height of water in vases to be set at same level. The apparatus is mounted on moulded plastic base that measures 25 x 17.5cm. The experiment is performed by screwing in each vase, in turn, and filling with water to the same level. It will be seen that the given height of water will result in the same deflection of pointer whatever shape of the vase.

Test your student's geology skills with this educational and fun activity. Students receive a bag of unlabeled rock specimens, then must test for physical and chemical properties in order to identify each rock sample. The easy-to-follow flowchart aids students in their classification decisions.
Catalog Number:
(470157-278)
Description:
This product is a small-sized model unit used for explaining the principle of a planetary gear. By setting the internal sun and pinion gears into motion (input or fixed), you can get the different outputs from acceleration, deceleration and reverse. Comes equipped with a storage case holding 10 Planetary Gear Demonstrators. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimentions: 24L x 14W x 14H cm ; Weight: 3kg
